When AI recommends parts, make it recommend yours.

PistonsAI plugs aftermarket catalogs into Claude, ChatGPT and Copilot, so every parts question gets a fitment-verified answer with live pricing and a link to your store.

Fitment-verified answers, live pricing and your checkout, inside every AI assistant.

Buyers are moving to AI. Specialty parts aren’t connected yet.

AI assistants now connect to live stores and data through MCP. General retail is wiring in fast. The specialty aftermarket has no layer of its own.
